Setting Output Controls Specifies convergence tolerances Provides options for terminating analyses Output controls, as their name indicates, control the amount and nature of output from an analysis. There are two primary output controls: Table 2.16 Output Controls Commands Command GUI Menu Paths OUTRES Main Menu> Preprocessor> Loads> Load Step Opts> Output Ctrls> DB/Results File 60 Purpose Controls what ANSYS writes to the database Release 13.0 - © SAS IP, Inc.

The example below illustrates using OUTRES and OUTPR: OUTRES,ALL,5 ! Writes all data every 5th substep OUTPR,NSOL,LAST ! Prints nodal solution for last substep only You can issue a series of OUTPR and OUTRES commands (up to 50 of them combined) to meticulously control the solution output, but be aware that the order in which they are issued is important. For example, the commands shown below will write all data to the database and results file every 10th substep and nodal solution data every fifth substep. OUTRES,ALL,10 OUTRES,NSOL,5 However, if you reverse the order of the commands (as shown below), the second command essentially overrides the first, resulting in all data being written every 10th substep and nothing every 5th substep. OUTRES,NSOL,5 OUTRES,ALL,10 As another example, OUTRES,NSOL,10 OUTRES,NSOL,ALL,TIP writes the solution at all DOFs every 10th substep and the solution at the node component "TIP" every substep. Again, if you reverse these you will only obtain output at all DOF every 10th substep. Note The program default for writing out solution data for all elements depends on analysis type; see the description of OUTRES in the Command Reference. To restrict the solution data that is written out, use OUTRES to selectively suppress (FREQ = NONE) the writing of solution data, or first suppress the writing of all solution data (OUTRES,ALL,NONE) and then selectively turn on the writing of solution data with subsequent OUTRES commands. A third output control command, ERESX, allows you to review element integration point values in the postprocessor.
